In an illustrative embodiment of the invention a system and method provides a substantially most efficient use of Solar power, the charging of stored energy devices, the discharging of stored energy devices, engine generator power, utility power and total and partial energy consumption and management.

In a particular illustrative embodiment, a controller having a linear programming computer program is provided for controlling the combined use of natural gas engines, diesel/natural gas duel fuel engines and battery power stored in a battery for energy for management in supplying energy to a system load being serviced by a combination of the natural gas engines, the diesel/natural gas duel fuel and the battery power.

A tutorial and description of the use of linear programming that can be adapted and used in one particular illustrative embodiment of the present invention is described in the book Linear programming, by Vasek Chvatal, W. H. Freeman and Company, New York, 1983. An example how to use of using linear programming to find an optimal fuel mixture for each generator at each time period and under each scenario using linear programming; and repeating the previous two steps as long as the fuel mixture obtained from the linear programming solution changes is shown in U.S. Pat. No. 6,021,402 to Takriti, which is hereby incorporated herein by reference in its entirety. An example of an energy management system that uses an expert system as an energy management system uses an expert engine and a numerical solver to determine an optimal manner of using and controlling the various energy consumption, producing and storage equipment in a plant/communities in order to for example reduce energy costs within the plant, and is especially applicable to plants that require or that are capable of using and/or producing different types of energy at different times. The energy management system operates the various energy manufacturing and energy usage components of the plant to minimize the cost of energy over time, or at various different times, while still meeting certain constraints or requirements within the operational system, such as producing a certain amount of heat or cooling, a certain power level, a certain level of production, etc. in U.S. Pat. No. 9,335,748 to Francino, which is hereby incorporated herein by reference in its entirety. In another particular illustrative embodiment of the invention, the Load Sharing Processor of the present invention is programmed as an expert system to perform energy management as described herein. In another particular illustrative embodiment of the invention, the Load Sharing Processor of the present invention is programmed as a neural network to perform energy management as described herein.

Systems and methods have been provided for combining natural gas generators and diesel fuel generators on the same electrical bus power land drill rigs. The good points of this arrangement is it enables a drilling contractor make use of very cheap locally produced natural gas to run the engine—generation needs for the drilling activities, thus greatly reducing expenses to operate a land drilling rig. The problem with this arrangement is that the natural gas generator has very poor speed response and cannot handle the high transient loads such as raising a draw works. To get even close to the high transient required response, the natural gas engine-generator is typically pre-loaded to 25-75% which consumes additional gas and wears out the gas generator out prematurely due to the continuous duty cycle.

In a particular illustrative embodiment of the invention, a system and method provide a solution by adding a battery to the system with ad DC-AC converter to allow fast transient response of the electrical system while solely operating with the natural gas engine-generator. On land based oil rigs, natural gas is relatively low cost and readily accessible as a by-product of operating the oil rig.

Dual fuel engines run on diesel and natural gas simultaneously. Using a dual fuel engine can reduce fuel cost per rig per month as it uses natural gas from the oil rig and when use in conjunction with the Hybrid Power Generation System disclosed herein is used intermittently as needed rather than being preload and continuously running, and thus has a lower duty cycle. Continuously running the natural gas engine during preload both wastes natural gas and shortens the life of the natural gas engine as it is worn out from running all the time during preload.

FIG. 1 depicts a particular illustrative embodiment of the invention as a system provided using a computer program for energy management. The computer program is a linear program. In another illustrative embodiment, the computer program can be but is not limited to a neural network and an expert system.

In another illustrative embodiment the battery is not used. In another particular illustrative embodiment of the invention two diesel fuel engine generators are combined with a duel fuel engine generator and a battery.
